Answer
The microscopic functional units of the kidney are called **nephrons**. Each kidney contains a vast number of nephrons, which are responsible for filtering blood, removing waste products, and regulating the balance of water and electrolytes in the body.
The exact number of nephrons in each kidney can vary among individuals, but on average, a human kidney is estimated to contain around **one million nephrons**. These nephrons are distributed throughout the renal cortex and are the primary units responsible for the kidney's crucial functions in maintaining internal balance and producing urine.
